Perhaps you should try some spelling variations:
22conflict management » conflict management, konflikt management, convict management
conflicts management » conflict management, contracts management, konflikt management
20 united » 10 united, 2002 united, 7 united
2 united » 12 united, 2 units, 2 unity

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((22conflict management) OR (conflicts management)) %((((20 united) OR (11 united))) OR (2 united)) states%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22conflict management) OR (conflicts management)) %((((20 united) or (11 united))) or (2 united)) states%22*".
